TECHNICAL FIELD

The present invention is directed to a hair removing device forepilating hairs from a user's skin, and more particularly to a hairremoving device with a detachable epilator head.

BACKGROUND ART

U.S. Pat. No. 4,960,422 discloses a hair removing device having adetachable epilator head that can be separated from a grip housing forcleaning the head, or for replacement with an analogous shaving head. Arotary motor is incorporated in the housing to provide a driving forceof epilating or shaving the hairs. Due to the detachable nature of thedevice, the housing also includes a gear which is driven by the motorand is responsible for detachable meshing engagement with an associatedgear provided in the epilator head or the shaving head. That is, theepilator head is drivingly connected to the motor by meshing engagementof the gears when the epilator head is attached to the housing. Withthis gear connection, however, the device suffers from a strictdimensional tolerance between the gears, i.e., a distance between theaxes of the gears for successfully transmitting the driving force fromthe motor to movable members in the head, which in turn requires acorrespondingly strict detachable connection between the housing and thedetachable head. Further, when the head is operating under a heavy load,the gear connection is likely to transmit vibrations occurring in theheavy load operation of the head directly to the housing, therebygenerating harsh vibrations which detract from a comfortable operationby the user grasping the housing.

DISCLOSURE OF THE INVENTION

The above problem has been reduced in the present invention whichprovides an improved hair removing device which is capable of givingdesign flexibility to the connection between a housing and a detachableepilator head, without requiring a strict driving connection between amotor in the housing and a drive mechanism in the head. The hairremoving device in accordance with the present invention includes thehousing incorporating the rotary motor, and the epilator head detachableto the housing. The epilator head carries epilation members forepilation of a user's hairs and includes a drive mechanism powered bythe motor to actuate the epilation members. The motor has an outputrotor fixedly carrying a noncircular joint. The drive mechanism includesa coupler which is detachably connected to the joint to receive therotary motion of the motor. The coupler is arranged coaxially with thejoint and is movable along the axis of the joint together with theepilator head into and out of engagement with and from the joint, andthe coupler is slidable along the axis of the joint while keeping thedriving connection therebetween. Thus, the driving connection betweenthe head and the motor can be established or disconnected simply bymoving the coupler towards and away from the joint, while givingsufficient tolerance in the axial direction of the joint for keeping thedriving connection. With this result, the driving connection can beeasily established for successfully driving the epilation members evenif there should be some gap in a mounting structure between the housingand the epilator head. Further, this simple slidable driving connectioncan be free from a harsh meshing engagement as seen in the gearconnection, thereby avoiding the transmission of harsh vibrations fromthe epilator head to the housing for assuring a comfortable operation,in addition to reducing a noise.

Preferably, the coupler is in the form of a sleeve defining therein asocket hole into which the joint fits. The coupler is recessed from abottom end of the epilator head such that the epilator head detachedfrom the housing can be placed upright on a supporting surface with thecoupler concealed in the bottom of the head.

The epilator head is preferred to carry a cylinder having a center axisalong which a plurality of the epilation members are arranged. The drivemechanism includes a first linkage leading from the coupler for shiftingthe epilation members along the center axis towards and away from oneanother in order to pinch the hairs between the adjacent epilationmembers and at the same time for rotating the cylinder about the centeraxis to pluck the hairs pinched between the members. The drive mechanismalso includes a second linkage leading from the coupler for oscillatingthe cylinder along the center axis to give optimum hair epilationefficiency. The cylinder is arranged to have its center axis lyingsubstantially in a coplanar relation with the axis of the joint suchthat the cylinder can be assembled together with the coupler and thedriving linkages into the epilator head of reduced thickness.

The coupler of the epilator head may be formed integrally with a coaxialpinion which engages with a gear wheel forming a common part of thefirst and second linkages for packing the parts of the linkages into alimited space within the epilator head.

Further, the epilator head includes a base detachable to the housing anda frame mounting thereon a plurality of gears forming the first andsecond linkages in addition to the cylinder. The frame is supported tothe base by way of spring means to be movable relative to the baseagainst the bias of the spring means. Thus, vibrations occurring in theoperation of the epilator head can be effectively absorbed by the springmeans so as to make the housing relatively free from the vibrations,assuring a comfortable handling of the device.

The frame is movable in a direction along the axis of the joint togetherwith the cylinder, i.e., floatingly supported to the base so that thecylinder can be depressed upon contact with the user's skin for easy andoptimum epilation efficiency. The frame is movable also in a directionof the center axis for successfully absorbing the vibrations occurringin the axial direction of the cylinder due to the oscillating movementof the cylinder.

The device may include a shaving head which is selectively detachable tothe housing in place of the epilator head. The shaving head carries acutter and includes a shaving drive mechanism powered by the motor tomove the cutter for cutting the hairs. The shaving drive mechanismincludes a shaving coupler which is basically identical to the couplerof the epilator head for detachable driving connection to the joint onthe side of the housing. Thus, the shaving head can be selectivelyreplaced for the epilator head for cutting relatively long hairs priorto epilating the hairs by use of the epilator head.

In this regard, the coupler of the shaving head may be formed integrallywith an eccentric cam which engages with a reciprocator carrying thecutter for translating the rotary motion of the motor into areciprocating movement of the cutter.

Further, the shaving drive mechanism is designed to translate the rotarymotion of the motor directly, i.e., without any intervening reductiongear, into the reciprocating movement of the cutter such that the cuttercan reciprocate at a frequency higher than a rotational speed at whichthe cylinder of the epilator head rotates about the center axis.

These and still other objects and advantageous features of the presentinvention will become more apparent from the following detaileddescription of the preferred embodiment when taken in conjunction withthe attached drawings.

DETAILED DESCRIPTION OF THE EMBODIMENT

Referring now to FIGS. 1 and 10, there is shown a hand-held hairremoving device in accordance with a preferred embodiment of the presentinvention. The device has a housing 10 which is designed to be graspedby a user's hand and to detachably mount thereon an epilator head 30 anda shaving head 300 selectively for epilating or plucking the hairs froma user's skin and cutting the hairs prior to epilating the hairs. Thehousing 10 accommodates an electric rotary motor 20 having a outputrotor shaft 21 extending vertically in alignment with a center verticalaxis of the housing for detachable driving connection to the epilatorhead 30 and shaving head 300 selectively mounted on top of the housing10. The epilator head 30 and the shaving head 300 are analogous in itsshape having an elongated width extending in a perpendicular relation tothe vertical axis of the housing 10. The epilator head 30 carries arotary cylinder 40 which is driven to rotate about its center axis,i.e., the horizontal axis of the head for plucking the hair, as shown inFIG. 1, while the shaving head 300 carries an outer shearing foil 310and an inner cutter 320 which is driven to reciprocate along thehorizontal axis of the head in a shearing engagement the shearing foil310 for cutting the hairs, as shown in FIG. 10.

The output rotor shaft 21 is fitted with a noncircular joint 22 having apolygonal section for driving connection with an associated coupler 130,430 provided on the side of the epilator head 30 or the shaving head300. The coupler 130, 430 is in the form of a sleeve having a sockethole for receiving the joint 22 such that the coupler 130, 430 isslidable along the axis of the joint 22 or the rotor shaft 21 whilekeeping the driving connection therebetween. The motor 20 is energizedeither by an A.C. mains or by an incorporated battery and is turned onand off by a switch button 12 on the housing 10. As shown in FIG. 4, thehousing 10 is assembled from a pair of housing halves 11 and encloses afixed chassis 110 which secures the motor 20 on its lower side andcarries a pair of sliders 120 on its upper surface for detachableconnection with the epilator head 30 or the shaving head 300. Eachslider 120 is movable horizontally on the upper surface of the chassis110 and is urged outwardly by a spring 111 until a stopper 122 engageswith an outer end of a corresponding slot 112 in the center of thechassis 110. The slider 120 has an opening 124 for receiving thereinanchor legs 32 or 332 projecting on the bottom of the epilator head 30or the shaving head 300 in such a manner that the anchor leg 32 or 332is hooked with one edge 125 of the opening. The slider 120 has a button126 that projects outwardly of the housing to be accessible by thefingers of the user grasping the housing 10. Thus, simply by pressingthe buttons 126 against the springs, the sliders 120 moves inwardly tounhook the anchor legs from the sliders 120 for detachment of the heads30 or 300 from the housing 10. The slider 120 is formed with an inclinedguide on the upper surface of the edge 125 for guiding the anchor leg 32into hooking engagement with the edge 125.

As shown in FIGS. 2, 3, 5, and 6, the epilator head 30 includes a baseframe 31 integrally formed with the anchor legs 32 for detachableconnection with the housing 10, and a head frame 37 supporting therotary cylinder 40 with a plurality of epilation members 61 and 71. Aswill be explained later in detail, the epilation members 61 and 71 arespaced along the center axis of the cylinder and are caused to shiftalong the axis towards and away from one another for pinching the hairsbetween the adjacent ones and releasing the hairs, thereby plucking thehairs pinched between the epilation members as the cylinder 40 rotates.

The epilator head 30 includes, in addition to the base frame 31 and thehead frame 37, a base cover 33, a gear support 34, a platform 35, and aretainer 36, all of which are assembled together into a single unitdetachable to the housing 10. A head cover 38 is detachably mounted tothe retainer 36 and is cooperative with the base cover 33 to conceal adrive mechanism of the epilator head 30, and has an opening 39 throughwhich the rotary cylinder 40 is exposed for contact with the skin of theuser. The gear support 34 carries a center bearing 131 rotatablysupporting an axle 132 which is secured at its lower end to the coupler130 and is secured at its upper end to a pinion 133. Also mounted on thegear support 34 is a gear wheel 134 which meshes with the pinion 133 andwith an intermediate gear 140 supported on the head frame 37. Theintermediate gear 140 is a combination gear having a small gear 141engaged with a face gear wheel 150 supported to the platform 35 andhaving a large gear 142 engaged with a gear wheel 144 integrally formedon one axial end of the cylinder 40 for rotating the cylinder 40 aboutits center horizontal axis. The face gear wheel 150 carries an eccentriccam 151 which engages into a follower cavity 137 in the bottom of thehead frame 37 in order to transform the rotary motion of the gear wheel150, i.e., the motor 20 into an oscillating movement of the cylinder 40along its center axis for maximizing the chance of plucking the hairs onthe surface of the cylinder 40.

The head frame 37 has an axle 138 which extends between a main-frame37-1 and a sub-frame 37-2 which are assembled together with theintermediate gear 140 interposed therebetween. The head frame 37 issupported to the platform 35 and is driven to oscillate along the axlerelative to the platform 35 or the base frame 31 while the cylinder 40is rotated. Thus, the driving linkage of the epilator head 30 includes afirst linkage leading from the coupler 130 to the gear wheel 144 forrotating the cylinder 40 and at the same time shifting the epilationmembers 61 and 71 for epilation of the hairs, and also includes a secondlinkage leading from the common coupler 130 to the face gear wheel 150for oscillating the cylinder 40 along its center axis in synchronouswith the rotation of the cylinder.

Coil springs 160 are interposed between the base frame 31 and the gearsupport 34 so as to floatingly support the cylinder 40 in the verticaldirection, thereby enabling the cylinder 40 to be depressed while makingthe hair epilation. Further, coil springs 162 are interposed between thebase frame 31 and the platform 35 so as to floatingly support thecylinder 40 in the horizontal direction, thereby damping the oscillatingmovement of the cylinder 40 and therefore reducing the amount of theresulting vibration reaching the housing 10. Whereby, the user holdingthe housing 10 can be relatively free from the unpleasant vibrations forcomfortable epilating operation. The head cover 38 is hooked on theretainer 36 by means of release buttons 170 on opposite upper width endsof the retainer 36. As shown in FIGS. 5 and 6, each button 170 has hooks171 engageable with recesses 176 in the inner lower end of the headcover 38, and includes a leg 172 by which the button is secured to theretainer 36. When the button 170 is pressed against the bias of a coilspring 174 interposed between the button 170 and the retainer 36, thehooks 171 are disengaged from the recesses, thereby releasing the headcover 38 from the rest of the epilator head 30. It is noted in thisconnection that the coils springs 174 are also utilized to absorb thevibrations of the retainer 36 oscillating together with the cylinder 40,thereby preventing the vibrations from being transmitted to the housing10, through the bottom cover 33. That is, the coils springs 160, 162,and 174 are responsible for absorbing the vibrations of the cylinder 40to make the housing 10 relatively free from the vibrations, assuring thecomfortable epilating operation. Although the illustrated embodimentdiscloses the use of the coil springs, the present invention should notlimited to the use of the coil springs and may equally use any otherelastic members such as a rubber or other types of springs.

The rotary cylinder 40 carries a plurality of hair pinching row units 50which are evenly spaced around the circumference of the cylinder. Asbest in FIGS. 8 and 9, each row unit 50 includes four stationary blades61 which are aligned along the axis of the cylinder, four movable blades71 which alternate the stationary blades, and three skin guides 80interposed between the adjacent stationary blades 61. These members arecommonly supported to a single metal-made holder plate 90 to define aself-sustained sub-assembly which is easily fitted around the cylinder40. The movable blades 71 are caused to pivot about an axisperpendicular to the center axis of the rotary cylinder 40 to open andclose the gap between the adjacent blades 61 and 71 as the rotarycylinder 40 rotates about the axis, thereby catching and pinching thehairs between the blades. The closure of the blades 61 and 71 are keptover a certain angular displacement around the axis, i.e., a fraction ofone rotation of the rotary cylinder 40, thereby pulling the hairspinched between the blades 61 and 71 in a tangential direction of thecylinder 40 for plucking the hairs. Because of the above hair epilationfunction, the blades 61 and 71 are referred to generally as theepilation members in the description and claims.

As shown in FIG. 6, the two stationary blades 61 are shaped from a metalplate into an integrated piece 60 in which the blades 61 are inseparablycontinuous with one another through a pair of beams 62. The skin guide80 is molded from a plastic material to have an arcuate surface 81 onits top for smooth contact with the skin of the user, and an anchor stud84 which projects to be press-fitted into a corresponding hole 91 of theholder plate 90 by the use of resiliency inherently given to the moldedpart. Formed at the opposite side of the skin guide 80 are grips 85which presses the beams 62 of the integrated piece 60 against the holderplate 90 so as to secure the stationary blades 61 to the holder plate atthe same time as the skin guide 80 is secured to the plate. The movableblade 71 is made of a metal and has a leg 72 of which lower end isinserted into a corresponding slot 92 of the plate 90 so that the legcomes into edge-contact selectively with either one of the oppositeedges of the slot 92. Formed on opposite of the leg are roundprojections 73 which cam over inclines of hooks 86 on the skin guide 80and are retained loosely behind the hooks 86. Whereby, the movableblades 71 can be pivotally supported to the holder plate 90 and completethe self-sustained sub-assembly which can be handled as one block whenassembling the pinching row units into the rotary cylinder 40. Twointegrated pieces 60, i.e., four stationary blades 61, four movableblades 71, and three skin guides 80 are supported to one holder plate 90to constitute each one of the plural pinching row units 50. After therow units 50 are placed in corresponding grooves 42 of the rotarycylinder 40, a corresponding number of pins 51 are inserted into thecylinder with each pin extending through the stationary blades 61, themovable blades 71, and the skin guides 80 to hold the row units inposition where, as best shown in FIG. 7, the movable blades 71 arelinked to actuator bars 101 and 102 which are inserted in the rotarycylinder 40 for imparting the pivotal movement to the movable blades 71for closing and opening the gap between the blades 61 and 71.

The actuator bars 101 and 102 are provided in number double the numberof the row units 50, i.e., eight bars in each longitudinal half of thecylinder 40 so that each bar is linked to actuate the two adjacentmovable blades 71 in each one of the row units 50, as shown in FIGS. 2and 7. That is, each actuator bar is linked to actuate the two movableblades 71 simultaneously to open and close in association with the twostationary blades 61 of each integrated piece 60. The actuator bars 101and 102 are held in the bottom of the groove 42 of the rotary cylinder40 to be axially slidable and are caused to move axially inwardly by theaction of cam rollers 180 as the cylinder 40 rotates, and to moveaxially outwardly by the action of return springs 120 as the cylinder 40further rotates, thereby repeating to close and open the blades duringone rotation of the cylinder.

The actuator bars 101 and 102 are each formed at its axially outer endwith an arcuate flange 103, 104 which extends circumferentially aboutthe longitudinal axis of the cylinder 40 for pressed contact with thecorresponding cam roller 180 over a prolonged period as the cylinder 40rotates. The cam roller 180 has an axial length so that it contactssimultaneously with the arcuate flanges 103 and 104 of the outer andinner circumferential rows, respectively. Thus, as the cylinder 40rotates, the movable blades 71 in two or three adjacent row units 50 ofthe cylinder 40 are simultaneously closed, while the movable blades 71in the other row units are opened. As shown in FIG. 5, the cam rollers180 are mounted respectively in holes 111 of the head frame 37 and arerotatable about individual pins 182. Each cam roller is pressed inwardlyagainst the actuator bar 101, 102 by spring props 183 secured to thehead frame 37.

The return springs 120 are provided on opposite ends of the cylinder 40for biasing the actuator bars 101 and 102 axially outwardly with onespring responsible for the eight actuator bars having the arcuateflanges 103 and 104 disposed on one end of the cylinder, and the otherspring for the remaining eight actuator bars having the arcuate flanges103 and 104 on the other end of the cylinder 40.

The row units 50 are arranged on the cylinder 40 as being offset in theaxial direction relative to each other so that the pairs of thestationary blade 61 and the movable blade 71 in anyone of the row unitsare staggered with the other pairs of the other row units with respectto the longitudinal axis of the cylinder, so that all the blade pairsare differently positioned with respect to the longitudinal axis of thecylinder for maximum plucking efficiency.

Now referring to FIGS. 10 to 13, the shaving head 300 is explained indetail. The shaving head 300 includes a base frame 331 integrally formedwith the anchor legs 332 for detachable connection with the housing 10,a head frame 337 carrying the inner cutter 320, and a head cover 338carrying the outer shearing foil 310. The base frame 331 and the headframe 337 are secured together with a base cover 333 to constitute asingle unit detachable to the housing 10, while the head cover 338 isdetachable to the base cover 333 by means of a release button 370. Theshaving head 300 includes, in addition to the base frame 331, the headframe 337 and the base cover 333, a closure plate 335, and a retainer336, all of which are assembled together into a single unit detachableto the housing 10. The head cover 338 is cooperative with the base cover333 to conceal a shaving drive mechanism of the shaving head 300. Thebase frame 331 holds a bearing 431 rotatably supporting an axle 432which is secured at is lower end to the shaving coupler 130 forconnection with the joint 22 on the side of the housing 10, and which issecured at its upper end to an eccentric cam 433 with a pin 434eccentric to the axle 432. The head frame 337 carries a reciprocator 350with a center stud 351 to which the inner cutter 320 is attached. Thereciprocator 350 is formed on its opposite width ends with resilientarms 352 by which the reciprocator 350 is mounted on the head frame 337so that a center rigid section 354 including the stud 351 is movablealong a width axis of the shaving head 300. The eccentric pin 434 fitsinto the center rigid section 354 so as to translate the rotary motionof the coupler 430, i.e., the motor 20 into the reciprocating motion ofthe inner cutter 320 for shaving the hairs with the outer shearing foil310. Thus, the drive mechanism of the shaving head 300 is established bythe coupler 130, the eccentric cam 433, the pin 434 and the reciprocator350. In this regard, the drive mechanism of the shaving head translatesthe rotary motion of the motor directly into the reciprocating motion ofthe cutter, i.e., without any intervening reducing gear such that thecutter can reciprocate at a frequency higher than a rotational speed atwhich the cylinder of the epilator head rotates about the center axis.

The closure plate 335 is fitted to close the upper opening of the headframe 337 while allowing the portions of the recitprocator 350 toproject on the closure plate. The retainer 336 is placed over theclosure plate 335 to cover the connections of the resilient arms 352 tothe head frame 337 as well as to support a seal ring fitted around thestud 351. The release button 370 is supported by the retainer 336 and isurged outwardly by means of a spring 374. When the button 370 is pressedinward, it is disengaged from the head cover 338 for detachment of thehead cover from the rest of the shaving head.

The shaving head 300 additionally includes a trimmer unit 380 forcutting relatively long hairs. The trimmer unit 380 includes a movablecutter 381 which is drivingly connected to the stud 351 by way of afitting 356 attached to the stud 351.

The shaving head 300 of the illustrated structure is shown only for anexample, and therefore the present invention should not be limited tothis specific structure of the shaving head and could be equally appliedto shaving heads of any other structure provided that at least onecutting element is powered by the rotary motion received at the coupler130 which is detachably connected to the non-circular joint 30 on theside of the housing 10.

Further, it should be noted that the joint 22 and the associated coupler130 and 430 should not be limited to have the illustrated squaresection, and could be shaped to have any other analogous section such astriangular, polygonal or elliptic section.
